The other engine choice is a 2.7-liter V6 mated to a five-speed automatic, the only V6 engine in this class according to Kia. With 182-horsepower at 6000 rpm and 182 lb.-ft. of torque at 4000 rpm, there is not much of a performance advantage to the V6, maybe a second or so improvement in acceleration. The real reason to choose the V6 is the added refinement. Where the four-cylinder is noisy, the V6 is smooth and quiet. The five-speed automatic is also more pleasant, with shifts noticeable only by looking at the tach. In addition, the V6 is available in both LX and EX trims. Forgo the third row, and you can get a V6 Rondo for less than $19,000.
